For just a string, many people will recommend NSUserDefaults.

If you want to use the AppDelegate, the answer overlaps this question Call a function in AppDelegate?

Here is my answer

You can create a header file that has a macro to the AppDelegate

GlobalData.h

#import "AppDelegate.h"
#define APPDELEGATE (AppDelegate *)[[UIApplication sharedApplication] delegate]

Then use it in any class

#import "GlobalData.h"

// to gain access to the delegate
AppDelegate * appDelegate = APPDELEGATE;

To access your string (assume it is a property called globalString)

appDelegate.globalString;

I use this approach because I can then store more #define's to some global constants (ie soundFXVolume - #define SOUND_FX_V 0.6)
